This Appl does not work in Mac OS X 10.9.5 Mavericks.
On the right side of the Yellow Pages window, information about individual businesses NEVER appears. I am using Mac OS X 10.9.5 Mavericks on a Mac Pro tower. Mac OS X 10.9.5 has a bug in it that affects some applications. Perhaps it is messing up Yellow Pages 2.1 for those using Mavericks 10.9.5. Please look into this. Your APPL is useless to me, as it provides no information for any individual business, regardless of the zip code or city name I enter. Please fix this. Note that someone else is complaining about the same problem in the user comments on the AppStore. Please fix.
